4. INSTALLATION
Before you proceed, please ensure the specifications and design of your fiber cabling solution. The patch cords to be installed
must match with the installed wall cabling.
1. Try not to mix cords of different core diameters. Patch cords must be of the same or higher bandwidth as the pre
installed wall cabling. System performance regarding distances cannot be guaranteed if lower rated patch cords are used.
2. Kinks, snags, pinches and poor contacts can significantly reduce the performance of a fiber patch cord.
3. The minimum bend radius for optical fiber patch cords varies with cord diameter. For 3.0 mm cords the minimum
un-loaded bend radius is 1.4 in (3.5 cm). Exceeding the bend radius can result in significant additional loss and adverse
impact on channel performance.
4. Try not to use excessive force during the patching process. This can stress the cords and connectors, resulting in reducing
their performance.
5. Bundling and tying patch cords gives the panel a neat appearance but tight bundling increases the risk of pinching.
6. Do not tighten ties beyond the point where individual cords can rotate freely. Use only specially designed products
manufactured for this purpose. This is the only way to ensure there are no tangles, kinks or strains.
7. Please remember to label the cords. These will identify pair modularity and tell technicians where the other end of the
cable is terminated. TIA-606-B requires that labels are visible and durable. They must be easily read by anyone carrying
out work on the panel.
REMOVING A PATCH CORD
- Locate the existing circuit on both fields of the equipment room (ER)
- Unplug the patch cord and cover the male connector with a dust cap
- Cover the open female port with a dust cover - some adapter ports have spring-loaded covers that automatically cover
the port
- Gently lift the cord vertically, taking up slack until the remaining fiber cord is detected
- Gently removing it from the cable pathways or however it was secured in that position.
ADDING A PATCH CORD
- Identify the location where the cord has to be installed
- Insert one end of the patch cord into the fiber coupling
- Labeling Fiber Optic Connecting Hardware and Cords should conform to TIA-606-B Cabling system administration,
labeling and records are also covered in ISO/IEC 14763-1
- Properly route the patch cord and secure the cable with the specified products for fiber.
- Plug the other end of the patch cord into the fiber coupling to begin the transmission of data.
- NOTE : Optical fiber cords of different types and specifications should not be mixed. Please note the color-
coding of connectors for different fiber specs to make it easy to avoid confusion.
